OBJECTIVES: Worldwide, only 5% of all salivary gland tumours are reported in children and 35-50% of these are malignant. According to the Finnish Cancer Registry, 15 children were diagnosed with salivary gland cancer (SGC) during 1990-2009 in Finland. There are no previous studies available on the histopathology, treatment, and survival of patients with these rare malignancies in Finland.
METHODS: Retrospective patient and tumour data covering the past 20 years were retrieved from the five University Hospitals in Finland. Ten paediatric SGC patients with a median age of 14 years (range, 9-19 years) and with available adequate patient data were included. The series comprised four boys and six girls. Follow-up time varied from five months to 14 years.
RESULTS: Two patients had a history of a previous malignancy. The majority of cases had a parotid gland cancer (7/10), and mucoepidermoid carcinoma was the most common histological subtype (5/10). All patients presented with Stage I-II disease and were treated surgically with curative intent. One patient with a Stage I mucoepidermoid carcinoma of the parotid gland received postoperative radiotherapy. No recurrences were encountered and all patients were free of disease at the last follow up.
CONCLUSIONS: The individual treatment design for paediatric SGC should follow consistent treatment strategies. All patients in the present study had low-grade tumours with a favourable prognosis. Since paediatric SGC is infrequent worldwide, the diagnostics, treatment, and follow up should be centralized in multidisciplinary Head and Neck Centres.
